Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679918, here are decompositions:

19 + 8679899 = 8679918
31 + 8679887 = 8679918
47 + 8679871 = 8679918
127 + 8679791 = 8679918
151 + 8679767 = 8679918
179 + 8679739 = 8679918
241 + 8679677 = 8679918
277 + 8679641 = 8679918

Showing the first eight; more decompositions exist.
